To all whom it may concern:

the it known that I, Auntie Johns Minne- Li citizen of France, residingat Paris, in. the Republic of France, have invented certain new anduseful. improvements in l einountahle Rims for Vehiele iires; and I dohereby declare "the following to he a full, clear, and. exactdescription of theinvention, such as will enable others skilled in theart to which it npperteins to make and use the some.

The present invention relates to demount- :ihle rims for vehicletiresand proposes an rims may he made of an undivided contractile body to theend that {L11 easy and quick niounting'or deinonnting of the tire may beeffected and herein such changes may he made Without the en'iployinentof mechanical appliances.

A known structure of demonntable rim of the type in question comprisesa, divided ring which permits of contraction thereoti but this divisionin the ring body is a source of considerable Weakness, and there is thefurther disadvantage that tools are news sery to bloc-h the rim againstthe tire. The present invention avoids these dis-ad vantages withhnvingthe greater portion of the rim unbroken, zinthits ends connectedby a segmental section; said section connections permitting of thecontraction of the rim; and the "whole blocked against the tire simplyby pressure againstsaid section with bend or foot. A

The mounting of av tire onit-he rim is done in the following1na'nner:--'ihe rim sect-ion alis' pushed inwardly of the rimcircumference to the position shown in Fig. 2 and the tine is thenplaced in position. The rim sections 2 are then. pressed by hand againstthe tire and simultaneous with this movement the section 4 is forced. inplace by pressing with the'tioot, and such pi essnre being prefemhlydirected against one oi the double hinges. In demounting the operationsare deflated, the

The hinges 5 I above described the ground, and this port with thesectionsl 2 pressed inwardly,

in the arrangement shown in 4 to 6 the rim consists of a relativelylarge and unbroken section Z the ends 8 of which are connected by arelatively short segmental sectionil through the medium of a singlehinge 10, and n double hinge ilgisnid double hinge comprising a, link 12which thus decreasing the pern'iits oi the necessary contraction of therun, as shown in F both cases the segn'ient 4i of the rim is zilwnvsheld strongly in position through the tinted tire, which pressurefurther tends to close the ends of the other sections in each of the:irrun ements the ends oi? the mental sections meet squarely no to givea smooth and Uninterrupted tread for the tire. And the rim edges aredesigned to have 4: 1e tot-in necessary to their respective sc ool-toiltires; thus in Fig. 1 said rim is formed with clencher flanges 13 forclencher tires; and in the second en'ihodiment flanges 14. provide a:
